[0001] This application is based on a Chinese patent application with the corresponding application number 2024216792438, the application date of July 15, 2024, and the application title of "A Wireless Microphone". This application claims the priority of the above-mentioned Chinese patent application, and the entire content of the above-mentioned Chinese patent application is incorporated herein by reference. Technical Field

[0002] This application relates to the technical field of electronic devices, and particularly to a portable signal acquisition device. Background Art

[0003] With the rise of self-media, more and more people engage in shooting short videos, short dramas, interviews, etc. During the shooting process, people usually wear portable signal acquisition devices such as wireless microphones or action cameras to facilitate the acquisition of signals required for shooting, such as audio signals or image frames during shooting, in order to improve the shooting effect. However, in related technologies, the wearing effect and signal acquisition effect of portable signal acquisition devices are poor, affecting the user experience. Summary of the Utility Model

[0004] This application provides a portable signal acquisition device, which can improve the wearing effect and signal acquisition effect of the portable signal acquisition device, thereby enhancing the user experience.

[0005] The technical solution adopted in this application is as follows:

[0006] This application discloses a portable signal acquisition device, including a signal acquisition module for acquiring signals, a signal receiving module for processing the acquired signals, and a connecting member for connecting the signal acquisition module and the signal receiving module. The connecting member and the signal receiving module form an openable and closable clamping space. The connecting member has an inner concave surface forming the clamping space, and in the direction from the bottom end of the signal receiving module to the top end of the signal receiving module, at least part of the inner concave surface extends beyond the signal receiving module. The inner concave surface is located between the signal receiving module and the signal acquisition module, and the size of the signal acquisition module is smaller than the size of the signal receiving module. The portable signal acquisition device of this application can improve the wearing effect and signal acquisition effect of the portable signal acquisition device, thereby improving the user experience.

[0007] The portable signal acquisition device provided by this application has the following beneficial effects:

[0008] The portable signal acquisition device provided by the present application separates the signal acquisition module and the signal reception module, and connects the separated signal acquisition module and signal reception module through a connecting member. At the same time, since at least part of the concave surface of the connecting member forming the clamping space extends beyond the signal reception module, after the portable signal acquisition device is clamped and worn, the signal reception module can be completely hidden behind the clamping object such as the user's collar or brim of a hat, and only part of the connecting member and the signal acquisition module are exposed in front of the user's collar or brim. In this way, the original integral signal acquisition device is split into two parts with different sizes, and the concave surface of the connecting member is used to realize the reverse hidden wearing of the larger-sized signal reception module behind the clamping object, reducing the exposed area of the portable signal acquisition device and improving the wearing aesthetics of the portable signal acquisition device. At the same time, the smaller-sized signal acquisition module is exposed in front of the clamping object to avoid signal acquisition occlusion, thereby improving the signal acquisition effect of the portable signal acquisition device. Therefore, the portable signal acquisition device of the present application has both wearing aesthetics and good signal acquisition effects, and can enhance the user experience.

[0009] In addition, in the present application, the signal reception module can be supported by the user's body after being hidden behind the clamping object, so as to avoid problems such as the collar turning over during wearing caused by the excessive weight of the signal reception module when it is exposed in front of the clamping object in the related art, further improving the wearing aesthetics and wearing comfort of the portable signal acquisition device, and enhancing the user experience.

[0010] It should be noted that the portable signal acquisition device provided by the present application can collect any signals that the user needs to collect during use, such as audio signals, image signals or optical signals, etc. The collected signals include one or more combinations, and the present application does not limit this. In addition, the image signal may include at least one of dynamic photos, static photos and videos. Description of the Drawings

Detailed implementation manners

[0024] Next, the technical solutions in the present application will be clearly and completely described in conjunction with the accompanying drawings in the present application. It should be understood that the accompanying drawings in the present application are only for illustrative purposes, and it is understandable for those skilled in the art to omit some well-known structures and their descriptions in the drawings. At the same time, in the description of the present application, if there are descriptions of terms such as "upper", "lower", "left", "right", etc. indicating the orientation or position relationship, it is only based on the orientation or position relationship shown in the drawings, and is for the convenience of describing the present application and is a simplified description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Correspondingly, in the description of the present application, if there are descriptions such as "first", "second", etc., such descriptions are only used to distinguish different components, and cannot be understood as indicating or implying their relative importance, any order, or implicitly indicating the quantity of the indicated technical features.

[0025] With the rise of self-media, more and more people are engaged in shooting short videos, short dramas, interviews, etc. During the shooting process, people usually wear portable signal acquisition devices such as wireless microphones or action cameras. For example, for convenient shooting and sound collection, people usually wear a wireless microphone and clip the wireless microphone on the collar to make the wireless microphone close to the sound source to meet the sound collection requirements. For example, for convenient shooting of sports videos or recording vlogs, people usually wear an action camera, and people either hold the action camera by hand or fix the action camera on a holder such as clothing.

[0026] However, in the related art, whether it is a portable signal acquisition device such as a wireless microphone or an action camera, its signal acquisition modules such as the sound collection module or the camera shooting module are fixedly integrated with the signal receiving modules such as the microphone main body or the camera main body. In this way, during the video shooting process, when people wear a wireless microphone for sound collection, it is necessary to completely expose the microphone main body so that the sound pickup module is in a suitable sound collection position to meet the sound collection requirements. When people wear an action camera, it is necessary to completely expose the camera main body to facilitate the camera to capture a complete picture to meet the shooting requirements. However, due to the large volume of the signal receiving modules such as the microphone main body or the camera main body, and most signal receiving modules have trademark patterns, during the shooting process, the signal receiving module is eye-catching due to its large volume, and the prominent trademark pattern also appears obtrusive, affecting the shooting quality and causing disgust among the audience. In some official recordings or short dramas and short videos with requirements, this is unacceptable. If users want to avoid the large-volume signal receiving module from being eye-catching when wearing a wireless microphone or an action camera, they can only cover and wear the signal receiving module, but this will also cover the signal acquisition modules such as the sound collection module or the camera module, affecting the signal acquisition effects such as sound collection or shooting pictures. Therefore, the portable signal acquisition device in the related art has a poor wearing effect and a poor signal acquisition effect, resulting in a poor user experience.

[0027] Therefore, the present application provides a portable signal acquisition device 1, which can realize the hidden wearing of the signal receiving module 20 while exposing the signal acquisition module 10, so as to reduce the exposed area of the portable signal acquisition device 1 and improve the signal acquisition effect of the portable signal acquisition device 1, thereby enhancing the user experience and improving user satisfaction.

[0028] The portable signal acquisition device 1 provided by the present application will be introduced and described below with reference to the accompanying drawings of the specification.

[0029] See Figures 1 to 3, this application discloses a portable signal acquisition device 1, which includes a signal acquisition module 10 for acquiring signals, a signal receiving module 20 for processing the acquired signals, and a connecting member 30 for connecting the signal acquisition module 10 and the signal receiving module 20. The connecting member 30 and the signal receiving module 20 form an openable and closable clamping space 40. The connecting member 30 has a concave surface 31 that forms the clamping space 40. In the direction from the bottom end 20b of the signal receiving module 20 to the top end 20a of the signal receiving module 20, at least a part of the concave surface 31 extends beyond the signal receiving module 20. The concave surface 31 is located between the signal receiving module 20 and the signal acquisition module 10, and the size of the signal acquisition module 10 is smaller than the size of the signal receiving module 20. The portable signal acquisition device 1 of this application can improve the wearing effect and signal acquisition effect of the portable signal acquisition device 1, thereby improving the user experience.

[0030] It should be noted that the portable signal acquisition device 1 provided in this application can acquire any signals that the user needs to acquire during use, such as audio signals, image signals, or optical signals. The acquired signals include one or a combination of multiple types, and this application does not limit this. In addition, the image signal may include at least one of dynamic photos, static photos, and videos. For example, when acquiring an audio signal, the signal acquisition module 10 is an audio acquisition module, and the signal receiving module 20 is an audio receiving module. Optionally, the portable signal acquisition device 1 can be used as a wireless microphone, the signal acquisition module 10 is set as a microphone sound collection module, and the signal receiving module 20 is set as a microphone body. For example, when acquiring an image signal, the signal acquisition module 10 is an image acquisition module, and the signal receiving module 20 is an image receiving module. Optionally, the portable signal acquisition device 1 can be used as an action camera or a hidden camera, the signal acquisition module 10 is set as the camera module of the camera, and the signal receiving module 20 is set as the camera body. Of course, the portable signal acquisition device 1 can also acquire other signals, which will not be elaborated in this application.

[0031] It should also be noted that the connecting member 30 and the signal receiving module 20 cooperate to form an openable and closable clamping space 40, and the connecting member 30 has a concave surface 31 that communicates with the clamping space 40. The signal receiving module 20 has a top end 20a and a bottom end 20b that are oppositely arranged. In the direction from the bottom end 20b of the signal receiving module 20 to the top end 20a of the signal receiving module 20, at least a part of the concave surface 31 extends beyond the signal receiving module 20, and the concave surface 31 is located between the signal receiving module 20 and the signal acquisition module 10, and the size of the signal acquisition module 10 is smaller than the size of the signal receiving module 20.

[0032] It should be noted that the top 20a and the bottom 20b of the signal receiving module 20 can be relatively spaced apart along the X direction in the figure. The connecting member 30 can be connected to the top 20a of the signal receiving module 20 or any position of the signal receiving module 20. The signal receiving module 20 can be set to any shape such as circular, rectangular or polygonal, as long as it meets the needs of the user to wear it on the body, and the present application does not make any restrictions.

[0033] In the present application, the signal acquisition module 10 and the signal receiving module 20 are split and arranged, and the signal acquisition module 10 and the signal receiving module 20 are connected through the connecting member 30. The connecting member 30 can be set to any shape such as sheet-shaped, strip-shaped or rod-shaped, and the present application does not make any restrictions. The connecting member 30 can be hinged to the signal receiving module 20, and the connecting member 30 can have a part extending along the X direction, so that the connecting member 30 can rotate relative to the signal receiving module 20 to form a clamping space 40 spaced apart along the Y direction with the signal receiving module 20. The clamping space 40 can be used to accommodate any clamping object 60 such as the user's collar, brim of a hat or hair, etc., so as to fix the portable signal acquisition device 1. In some embodiments, an elastic reset member such as a spring or a spring piece can be further arranged between the connecting member 30 and the signal receiving module 20 to facilitate the opening and closing of the clamping space 40.

[0034] At the same time, the connecting member 30 has a concave surface 31 communicating with the clamping space 40, and the concave surface 31 is recessed in the connecting member 30 along the direction from the inside of the clamping space 40 to the outside of the clamping space 40. When the connecting member 30 is connected to the signal receiving module 20, the concave surface 31 extends beyond the edge of the signal receiving module 20. As an example, the concave surface 31 is higher than the edge of the top 20a of the signal receiving module 20 in the X direction. In this way, when the user wears the portable signal acquisition device 1, the wearing modes as shown in Figure 4 and Figure 5 can be formed. In the wearing modes in Figure 4 and Figure 5 , since in the direction from the bottom 20b of the signal receiving module 20 to the top 20a of the signal receiving module 20, at least part of the concave surface 31 extends beyond the signal receiving module 20, after the portable signal acquisition device 1 is worn, the signal receiving module 20 can be completely hidden behind the clamping object 60 such as the user's collar or brim of a hat, and only part of the connecting member 30 leaks out in front of the user's collar or brim of a hat, and the exposed size of the connecting member 30 is significantly smaller than the size of the hidden signal receiving module 20. Thus, through this reverse wearing mode of hiding the signal receiving module 20 behind the clamping object 60, the size of the portable signal acquisition device 1 exposed in the lens picture can be significantly reduced, realizing the hidden wearing of the portable signal acquisition device 1 and improving the beauty of being on camera.

[0035] Moreover, in order to improve the signal acquisition effect of the portable signal acquisition device 1, the signal acquisition module 10, which is separately arranged from the signal receiving module 20, is separately arranged on the exposed part of the connecting member 30. That is, the signal acquisition module 10 can be connected to any position of the connecting member 30, as long as the sound collecting hole of the signal acquisition module 10 is not blocked after the portable signal acquisition device 1 is worn. As an example, the signal acquisition module 10 is arranged on the connecting member 30 and the concave surface 31 is between the signal receiving module 20 and the signal acquisition module 10, so that the signal acquisition module 10 can expose the clamping object 60 and avoid being blocked, thereby clearly acquiring the captured sound through the signal acquisition module 10.

[0036] Furthermore, the size of the signal acquisition module 10 is also set to be smaller than the size of the signal receiving module 20. Among them, the size of the signal acquisition module 10 being smaller than the size of the signal receiving module 20 may include at least one of the volume size or the area size. As an example, the size of the signal acquisition module 10 may be smaller than the size of the signal receiving module 20 in any direction such as the thickness direction, the length direction, and the width direction of the signal receiving module 20 (for example, as shown in the X direction, Y direction, and Z direction in the figure). In this way, even if the signal acquisition module 10 is exposed after the portable signal acquisition device 1 is worn, the exposed size of the signal acquisition module 10 is relatively smaller than the exposed size of the signal receiving module 20 in the related art. Therefore, the overall size of the exposed part after the portable signal acquisition device 1 is worn is relatively smaller than the size of the hidden signal receiving module 20, and the exposed area after the portable signal acquisition device 1 is worn can be reduced.

[0037] Therefore, compared with the related art, it should be noted that in the portable signal acquisition device 1 provided in the present application, the signal acquisition module 10 and the signal receiving module 20 are split and arranged, and the split signal acquisition module 10 and signal receiving module 20 are connected by the connecting member 30. At the same time, since at least part of the concave surface 31 of the connecting member 30 forming the clamping space 40 extends beyond the signal receiving module 20, after the portable signal acquisition device 1 is clamped and worn, the signal receiving module 20 can be completely hidden behind the clamping object 60 such as the user's collar or brim, and only part of the connecting member 30 and the signal acquisition module 10 are exposed in front of the user's collar or brim. In this way, the original integral signal acquisition device is split into two parts with different sizes, and the concave surface 31 of the connecting member 30 is used to achieve the reverse hidden wearing of the larger-sized signal receiving module 20 behind the clamping object 60, reducing the exposed area of the portable signal acquisition device 1 and improving the wearing aesthetics of the portable signal acquisition device 1. At the same time, the smaller-sized signal acquisition module 10 is exposed in front of the clamping object 60 to avoid signal acquisition occlusion, thereby improving the signal acquisition effect of the portable signal acquisition device 1. Thus, the portable signal acquisition device 1 of the present application has both wearing aesthetics and good signal acquisition effects, and can improve the user experience.

[0038] In addition, in the present application, the signal receiving module 20 can be supported by the user's body after being hidden behind the clamping object 60, so as to avoid problems such as the wearing lapel caused by the excessive weight of the signal receiving module 20 leaking out in front of the clamping object 60 in the related art, further improving the wearing aesthetics and wearing comfort of the portable signal acquisition device 1, and enhancing the user experience.

[0039] See Figure 3 , in some embodiments, to improve the wearing effect of the portable signal acquisition device 1, the signal receiving module 20 has a clamping surface 21 forming the clamping space 40 and an outer side surface 22 opposite to the clamping surface 21. In the direction from the outer side surface 22 of the signal receiving module 20 to the clamping surface 21, at least part of the signal receiving module 20 overlaps with the signal acquisition module 10, and the signal acquisition module 10, the connecting member 30 and the signal receiving module 20 cooperate together to form the clamping space 40.

[0040] It should be noted that the signal receiving module 20 and the signal acquisition module 10 can be respectively arranged at both ends of the connecting member 30. As an example, the connecting member 30 can be arranged in a U shape or other arc shapes, so that the signal receiving module 20 and the signal acquisition module 10 can be arranged opposite to each other along the Y direction. In this way, the split signal receiving module 20 and signal acquisition module 10 can be connected by the connecting member 30, and the exposed signal acquisition module 10 can be used in cooperation with the connecting member 30 to jointly clamp a clamping object 60 such as a collar or a brim, so as to increase the clamping area of the clamping object 60 and improve the wearing stability of the portable signal acquisition device 1. Optionally, the central positions of the signal receiving module 20 and the signal acquisition module 10 are correspondingly arranged, so that the two are respectively on the opposite sides of the clamped position of the clamping object 60, so as to improve the clamping effect on the clamping object � Of course, in other embodiments, the signal acquisition module 10 can also be arranged at other positions of the connecting member 30, as long as the signal acquisition module 10 is not blocked to affect the signal acquisition effect after the portable signal acquisition device 1 is worn.

[0041] In some embodiments, to facilitate the connection of the connecting member 30 to the signal receiving module 20 and the signal acquisition module 10, the connecting member 30 includes a receiving connection portion 33 and an acquisition connection portion 32. The receiving connection portion 33 is connected to the signal receiving module 20. The acquisition connection portion 32 is connected between the receiving connection portion 33 and the signal acquisition module 10.

[0042] It should be noted that the receiving connection portion 33 and the acquisition connection portion 32 of the connecting member 30 can be disassembled and assembled, so as to facilitate replacement and production. At the same time, to improve the appearance smoothness and aesthetics of the connecting member 30, the receiving connection portion 33 and the acquisition connection portion 32 can also be arranged as an integrally formed structure, which is not limited in this application.

[0043] Among them, the receiving connection portion 33 and the signal receiving module 20 can be connected by various methods such as magnetic attraction cooperation, plug-in cooperation, threaded connection, adhesive fixation or welding fixation, etc., which are not limited in this application. The acquisition connection portion 32 and the signal acquisition module 10 can also be connected by various methods such as magnetic attraction cooperation, plug-in cooperation, threaded connection, adhesive fixation or welding fixation, etc., which are not limited in this application.

[0044] In some embodiments, to improve the connection stability between the connector 30 and the signal receiving module 20, in the direction from the top end 20a of the signal receiving module 20 to the bottom end 20b of the signal receiving module 20, the cross-sectional area of the receiving connection portion 33 gradually increases. As an example, the outer wall of the receiving connection portion 33 connected to the signal receiving module 20 gradually expands outward to increase the connection area between the connector 30 and the signal receiving module 20, thereby improving the connection stability between the connector 30 and the signal receiving module 20. At the same time, the outer surface 34 of the receiving connection portion 33 has a smooth line, which can also increase the aesthetic appearance.

[0045] In some embodiments, to improve the connection stability between the connector 30 and the signal acquisition module 20, in the direction from the top end 20a of the signal receiving module 20 to the bottom end 20b of the signal receiving module 20, the cross-sectional area of the acquisition connection portion 32 gradually increases. As an example, the outer wall of the acquisition connection portion 32 connected to the signal acquisition module 10 gradually expands outward to increase the connection area between the connector 30 and the signal acquisition module 10, thereby improving the connection stability between the connector 30 and the signal acquisition module 10. At the same time, the outer surface 34 of the acquisition connection portion 32 has a smooth line, which can also increase the aesthetic appearance.

[0046] In some embodiments, to facilitate the formation of the concave surface 31, the concave surface 31 is provided on at least one of the receiving connection portion 33 and the acquisition connection portion 32. Alternatively, the connector 30 further includes a transition connection portion connected between the receiving connection portion 33 and the acquisition connection portion 32, and the concave surface 31 is provided on the transition connection portion.

[0047] It should be noted that a corner can be formed by connecting the receiving connection portion 33 and the acquisition connection portion 32, and the concave surface 31 is provided at the corner, which can be formed by the cooperation of a part of the receiving connection portion 33 and a part of the acquisition connection portion 32. Alternatively, the receiving connection portion 33 and the acquisition connection portion 32 extend in different directions, and the concave surface 31 can be provided on either the receiving connection portion 33 or the acquisition connection portion 32, which is not limited in this application. Alternatively, the connector 30 may further include a transition connection portion connected between the receiving connection portion 33 and the acquisition connection portion 32, and the concave surface 31 is provided on the transition connection portion. As an example, the transition connection portion is provided as a U-shaped structure, and the receiving connection portion 33 and the acquisition connection portion 32 are oppositely arranged and respectively connected to both ends of the U-shaped structure.

[0048] In some embodiments, to facilitate the wearing of the portable signal acquisition device 1, in the direction from the outer side surface 22 of the signal receiving module 20 to the clamping surface 21, the concave surface 31 extends in an arc shape. With this setting, the inner wall of the clamping space 40 can form a smooth line to avoid pulling the clamped object 60 during the wearing process of the portable signal acquisition device 1, thereby facilitating the wearing of the portable signal acquisition device 1.

[0049] In some embodiments, to improve the aesthetics of the portable signal acquisition device 1, the connecting member 30 has an outer surface 34 disposed opposite to the concave surface 31, and the outer surface 34 of the connecting member 30 is smoothly transitioned from the receiving connection portion 33 to the acquisition connection portion 32. With this arrangement, the exposed part of the connecting member 30 after the portable signal acquisition device 1 is worn is in an arc shape with a smooth transition, making the overall appearance of the portable signal acquisition device 1 smooth after wearing and increasing the aesthetics. At the same time, with this arrangement, it is also possible to avoid the generation of sharp corners on the outer wall of the connecting member 30, reduce the appearance bump damage of the portable signal acquisition device 1, and avoid hurting the user.

[0050] In some embodiments, the connecting member connected between the signal acquisition module and the signal receiving module can have various forms.

[0051] Example 1: The connecting member includes an electronic wire harness. One end of the electronic wire harness is electrically connected to the signal acquisition module, and the other end of the electronic wire harness is electrically connected to the signal receiving module to transmit signals.

[0052] Example 2: The connecting member includes a connecting frame. The signal acquisition module and the signal receiving module are respectively fixed to the connecting frame. The connecting frame is provided with a concave surface, and the signal acquisition module and the signal receiving module are communicatively connected through a short-range communication module.

[0053] Example 3: The connecting member includes a connecting frame and an electronic wire harness. The connecting frame is connected between the signal acquisition module and the signal receiving module. The electronic wire harness is fixed to the connecting frame and extends along the connecting frame, and the two ends of the electronic wire harness are respectively connected to the signal acquisition module and the signal receiving module correspondingly.

[0054] In some embodiments, to facilitate the formation of a clamping space, the signal receiving module has a clamping surface for forming the clamping space and an outer side surface disposed opposite to the clamping surface. In the direction from the outer side surface of the signal receiving module towards the clamping surface, at least part of the signal acquisition module and the signal receiving module overlap, and the signal acquisition module, the connecting frame, and the signal receiving module cooperate together to form the clamping space.

[0055] It can be understood that the connecting frame can be elastic. In the direction from the outer side surface of the signal receiving module towards the clamping surface, the connecting frame is in an arc shape to facilitate the formation of the clamping space.

[0056] It can be understood that the connecting frame can be set as an integrally formed part.

[0057] In some embodiments, when the connecting member includes a connecting frame and an electronic wire harness, the connection structure where the connecting member is connected between the signal acquisition module and the signal receiving module includes: the housing of the signal acquisition module is provided with an acquisition connection hole, and one end of the connecting frame is connected to the acquisition connection hole to be fixed to the housing of the signal acquisition module. One end of the electronic wire harness passes through the acquisition connection hole and is electrically connected to the signal acquisition element in the signal acquisition module. The housing of the signal receiving module is provided with a receiving connection hole, and the other end of the connecting frame is connected to the receiving connection hole to be fixed to the housing of the signal receiving module. The other end of the electronic wire harness passes through the receiving connection hole and is electrically connected to the signal receiving element in the signal receiving module.

[0058] In some embodiments, the outer surface of the connecting frame may be covered with a sheath, and the electronic wire harness may be fixed between the connecting frame and the sheath.

[0059] Taking the portable signal acquisition device 1 as an example of a wireless microphone application below, that is, taking the signal receiving module as the microphone main body and the signal acquisition module as the sound collection module, the following will be elaborated.

[0060] See Figure 6 and Figure 7 , in some embodiments, the sound collection component 10 includes a sound collection housing 11 and an audio acquisition element 12 installed in the sound collection housing 11. The audio acquisition element 12 is used to acquire audio signals. The microphone main body 20 includes a microphone housing 23 and a processing element 24 installed in the microphone housing 23. The processing element 24 is used to process the acquired audio signals. Among them, the sound collection housing 11 and the microphone housing 23 are respectively connected to the connecting member 30.

[0061] Among them, the audio acquisition element 12 includes a diaphragm device. The processing element 24 includes a main circuit board. The processing element 24 and the audio acquisition element 12 can be connected through various short-distance communication methods such as Bluetooth, NFC, or wireless WIFI, etc. This application does not make any restrictions.

[0062] In some embodiments, the processing element 24 and the audio acquisition element 12 can also be connected through a wire. The wireless microphone may include an electronic wire harness 38. The electronic wire harness 38 is arranged in the connecting member 30 and extends along the connecting member 30. One end of the electronic wire harness 38 passes through the sound collection housing 11 and is connected to the audio acquisition element 12, and the other end of the electronic wire harness 38 passes through the microphone housing 23 and is connected to the processing element 24.

[0063] With such a setting, while using the connecting member 30 to realize the mechanical connection between the microphone housing 23 and the sound collection housing 11, it is also possible to complete the circuit connection between the processing element 24 and the audio acquisition element 12 through the electronic wire harness 38 built in the connecting member 30. This not only makes the assembly of the wireless microphone 1 convenient and efficient, but also makes the appearance of the wireless microphone 1 more concise due to the built-in electronic wire harness 38.

[0064] As an example, to simultaneously meet the installation requirements of the connector 30 and the electronic wire harness 38, the radio housing 11 is provided with a radio connection hole 15, and the radio connection hole is equivalent to the receiving connection hole. One end of the connector 30 is connected to the radio connection hole 15, and one end of the electronic wire harness 38 passes through the radio connection hole 15 and is connected to the audio acquisition element 12. Correspondingly, the microphone housing 23 is provided with a main body connection hole 25, and the main body connection hole 25 is equivalent to the acquisition connection hole 25. The other end of the connector 30 is connected to the main body connection hole 25, and the other end of the electronic wire harness 38 can also enter the microphone housing 23 through the main body connection hole 25 to be connected to the processing element 24.

[0065] In some embodiments, since some electronic components or other structures may be provided in the radio assembly 10 to collect audio signals or other required signals, and some electronic components or other structures may be provided in the microphone main body 20 to transmit or process the collected audio signals or other signals. When the radio housing 11 and the microphone housing 23 are respectively provided with connection holes to cooperate with the connection of the connector 30 or the electronic wire harness 38, it is also necessary to perform a sealing treatment between the connector 30 and the radio connection hole 15 of the radio housing 11, and a sealing treatment between the connector 30 and the main body connection hole 25 of the microphone housing 23. Optionally, the sealing treatment can be sealed by various methods such as setting a sealing ring, gluing, welding, thread fitting or interference fitting, and the present application does not make a limitation.

[0066] See Figure 6 and Figure 7 , in some embodiments, to position the electronic wire harness 38 to ensure reliable connection between the electronic wire harness 38 and the audio acquisition element 12 and the processing element 24, the wireless microphone may further include a limiting member 35.

[0067] Wherein, one end of the connector 30 connected to the radio connection hole 15 is set as the radio connection end, and one end of the connector 30 connected to the main body connection hole 25 is set as the main body connection end. Two limiting members 35 can be provided. The first limiting member 35 is connected between the radio connection end of the connector 30 and the electronic wire harness 38, and the first limiting member 35 is inserted into the radio connection hole 15 and fixed. The second limiting member 35 is connected between the main body connection end of the connector 30 and the electronic wire harness 38, and the second limiting member 35 is inserted into the main body connection hole 25 and fixed.

[0068] As an example, the limiting member 35 can be set as a tongue structure with a through hole. Among them, the limiting member 35 connected to the radio connection hole 15 is set as the radio tongue 35a, and the limiting member 35 connected to the main body connection hole 25 is set as the main body tongue 35b.

[0069] The sound receiving tongue 35a is fixed to the sound receiving connection end of the connecting member 30. The electronic wire harness 38 is fixed in the through hole of the sound receiving tongue 35a, and a part of the electronic wire harness 38 extends out through the through hole of the sound receiving tongue 35a as the sound receiving connection terminal. The main body tongue 35b is fixed to the main body connection end of the connecting member 30. The electronic wire harness 38 is fixed in the through hole of the main body tongue 35b, and a part of the electronic wire harness 38 extends out through the through hole of the main body tongue 35b as the main body connection terminal.

[0070] When assembling the connecting member 30 and the sound receiving assembly 10, the sound receiving tongue 35a can be directly inserted into the sound receiving connection hole 15 of the sound receiving housing 11. On the one hand, the connecting member 30 is fixed to the sound receiving housing 11, and on the other hand, the sound receiving connection end of the electronic wire harness 38 is docked with the audio acquisition element 12 in the sound receiving housing 11 to simultaneously complete the mechanical connection and the wire connection. When assembling the connecting member 30 and the microphone main body 20, the main body tongue 35b can be directly inserted into the main body connection hole 25 of the microphone housing 23. On the one hand, the connecting member 30 is fixed to the microphone housing 23, and on the other hand, the main body connection end of the electronic wire harness 38 is docked with the processing element 24 in the microphone housing 23 to simultaneously complete the mechanical connection and the wire connection.

[0071] Thus, the relative position between the connecting member 30 and the electronic wire harness 38 can be restricted by the limiting member 35 to prevent the virtual connection between the processing element 24 and the audio acquisition element 12 caused by the movement of the electronic wire harness 38, thereby ensuring the reliability of the wire connection. At the same time, the mechanical connection and the wire connection between the connecting member and the microphone main body and the sound receiving assembly can be completed through the cooperation between the limiting member 35 and the connection holes on the sound receiving housing 11 and the microphone housing 23, so as to simplify the installation.

[0072] In addition, when the connecting member 30 is connected to the microphone main body 20, the limiting member 35 can be inserted and hidden into the microphone housing 23. When the connecting member 30 is connected to the sound receiving assembly 10, the limiting member 35 can also be inserted and hidden into the sound receiving housing 11. In this way, while improving the connection reliability, the appearance of the wireless microphone 1 can be ensured, and at the same time, the size of the wireless microphone 1 leaking out during wearing can be further reduced.

[0073] In some embodiments, the outer wall of each limiting member 35 may be provided with a partially uneven fitting structure. Correspondingly, the inner wall of the sound receiving connection hole 15 and the main body connection hole 25 may be provided with a fitting and cooperating structure adapted to the fitting structure. In this way, the connection area between the limiting member 35 and each connection hole can be increased by using the fitting structure and the fitting and cooperating structure to improve the plugging stability. At the same time, the plugging sealing effect can also be improved by the mutual cooperation between the fitting structure and the fitting and cooperating structure. Of course, in some embodiments, a gluing process can also be used to fix and seal between the limiting member 35 and each connection hole, and the present application does not make any restrictions.

[0074] Still referring toFigure 6 and Figure 7 , in some embodiments, to improve the aesthetics of the wireless microphone 1, the wireless microphone 1 further includes a sheath 39 that covers the connecting member 30, the electronic wire harness 38, and the limiting member 35 to reduce the external cross-section of the wireless microphone 1 and improve the overall aesthetics and the connection sealing between parts.

[0075] Meanwhile, the sheath 39 covering the outer surface 34 of the connecting member 30 can be made of a soft material, such as a soft material like silicone or rubber, to increase the friction between the connecting member 30 and the clamping object 60 through the soft material, improve the clamping stability, and at the same time, the soft material can achieve a flexible connection with the clamping object 60 to reduce damage to the clamping object 60. In some other embodiments, a cavity can also be provided inside the connecting member 30 for installing the electronic wire harness 38 and the limiting member 35. Meanwhile, the outer surface material of the connecting member 30 is a soft material to serve the role of the sheath 39, and this application does not make any restrictions on this.

[0076] See Figure 8 and Figure 9 , in some embodiments, the electronic wire harness 38 can also be directly fixed to the connecting member 30 to cancel the limiting member 35, thereby reducing the covering volume of the sheath 39. As an example, the connecting member 30 can be set as a sheet or a strip, and the electronic wire harness 38 is laid and fixed on the wall surface of the strip-shaped connecting member 30 along the extending direction. The electronic wire harness 38 can be fixed to the connecting member 30 by means such as gluing, and this application does not make any restrictions. Optionally, the electronic wire harness 38 can be fixed to the inner wall of the connecting member 30 facing the clamping space 40 for hidden installation.

[0077] As an example, the connecting member 30 can also be set as a rod shape, and the electronic wire harness 38 is wound and fixed on the surface of the connecting member 30. The electronic wire harness 38 can be fixed to the connecting member 30 in various ways such as clockwise winding, counterclockwise winding, double-strand winding, or cross winding, and this application does not make any restrictions. Of course, the connecting member 30 can also be set in other slender shapes as long as it satisfies the installation of the electronic wire harness 38 and the connection between the microphone main body 20 and the sound collection component 10, and at the same time, the exposed area of the connecting member 30 is small after the wireless microphone 1 is worn. This application will not elaborate on other shapes of the connecting member 30.

[0078] With such a setting, since the limiting member 35 is removed, when the sheath 39 is used to wrap the connecting member 30 and the electronic wire harness 38, there is no need to wrap the limiting member 35 anymore, so as to reduce the volume of the formed sheath 39 (for example, the dimension of the sheath 39 in the Z direction in the figure is narrower), thereby being able to reduce the external leakage dimension of the connection part between the microphone main body 20 and the sound collection component 10, and further reducing the external leakage dimension after the wireless microphone 1 is worn, improving the wearing concealment effect and wearing aesthetics. As an example, the sheath 39 wraps around the connecting member 30 and the electronic wire harness 38 to form an integral connection structure, and this connection structure can be set as a U-shaped member with uniform thickness or other arc shapes.

[0079] In addition, since the limiting member 35 is removed, the electronic wire harness 38 and the connecting member 30 are directly fixed to form an integral body. Therefore, in order to avoid the virtual connection between the processing element 24 and the audio acquisition element 12 caused by the movement of the electronic wire harness 38, limiting portions 36 can be respectively provided at both ends of the connecting member 30. After the two ends of the connecting member 30 are respectively inserted into the sound collection housing 11 and the microphone housing 23, the connecting member 30, the sound collection housing 11 and the microphone housing 23 can be further fixed through the cooperation between the limiting portions 36 and the connection holes of each housing, which can not only improve the connection stability between the connecting member 30 and the microphone housing 23 and the sound collection housing 11, but also position the electronic wire harness 38 by positioning the connecting member 30, so as to improve the connection reliability between the electronic wire harness 38 and the processing element 24 and the audio acquisition element 12. As an example, concave portions can be provided on the outer walls at both ends of the connecting member 30 to form the limiting portions 36.

[0080] In some related technologies, the fixing method of the wireless microphone 1 is the opening and closing of a fixed angle formed by a rigid back clip and the main body through a spring. It not only has certain requirements for the size of the clamped object, but also the spring of the back clip is prone to failure during use. Therefore, referring to Figures 7 to 9 , in some embodiments, in order to enable the wireless microphone 1 to be worn on clamping objects 60 of different sizes, the connecting member 30 is elastic, and in the direction from the microphone main body 20 to the sound collection component 10, the connecting member 30 extends in an arc shape.

[0081] It should be noted that the connecting member 30 can be set as an elastic metal spring piece or a non-metal spring piece capable of having an opening and closing state, such as any spring piece of iron, aluminum, gold, silver, silica gel or rubber, etc., and the present application does not make any restrictions. The connecting member 30 can be set in a U shape to facilitate connecting the microphone main body 20 and the sound collection component 10 to form a clamping space 40.

[0082] In other embodiments, in order to extend the service life of the connecting member 30, the connecting member 30 includes a component made of shape memory alloy 37, or the connecting member 30 internally contains shape memory alloy 37 to form an elastic connection frame by using the shape memory alloy 37.

[0083] It should be noted that the shape memory alloy 37 includes a Nepal alloy composed of nickel and titanium, a copper-zinc-aluminum alloy, a nickel-titanium-silver alloy, etc., and the present application does not limit it. As long as this shape memory alloy 37 has a memory function, it can restore the initially set shape at normal temperature and has good resilience. In this way, by setting the shape memory alloy 37 skeleton, the smaller angle set initially can be used to make the sound collection component 10 and the microphone body 20 connected to both ends of the connecting member 30 close to each other. When in use, no matter whether a collar or other thickness of the clamping object 60 is placed into the clamping space 40, the shape memory alloy 37 will generate a stress towards the inside of the clamping space 40 to play a role in clamping and fixing the clamping object 60. And no matter whether excessive deformation occurs during the actual use process of this shape memory alloy 37, as long as it is within normal temperature, the shape memory alloy 37 can restore its initial shape, and there is no need to worry about the failure problem. Therefore, by setting the shape memory alloy 37 on the connecting member 30, the size limit of the clamping object 60 for the wireless microphone 1 can be relaxed and the service life of the connecting member 30 can be extended.

[0084] In addition, in some embodiments, the outer surface material of the connecting member 30 is a soft material, or the outer surface 34 of the connecting member 30 can be coated with a sheath of a soft material, such as a soft material like silicone or rubber, so as to increase the friction between the connecting member 30 and the clamping object 60 through the soft material, improve the clamping stability, and at the same time, a flexible connection with the clamping object 60 can be achieved through the soft material to reduce damage to the clamping object 60.

[0085] As an example, to facilitate the connection between the microphone body 20 and the sound collection component 10, the present application provides a connection component. The connection component includes an elastic skeleton, an electronic wire harness 38, and a sheath 39. The elastic skeleton is connected between the microphone body 20 and the sound collection component 10. The elastic skeleton and the microphone body 20 cooperate to form a clamping space 40, and the elastic skeleton is provided with a concave surface 31. Optionally, the elastic skeleton is made of the shape memory alloy 37. The electronic wire harness 38 is fixed to the elastic skeleton and extends along the elastic skeleton. The electronic wire harness 38 is used for the electrical connection between the microphone body 20 and the sound collection component 10 to transmit audio signals. The sheath 39 covers the outside of the elastic skeleton and the electronic wire harness 38, and both ends of the sheath 39 are in smooth transition with the microphone body 20 and / or the sound collection component 10 respectively.

[0086] Among them, the electronic wire harness 38 is parallel to the elastic skeleton made of the shape memory alloy 37. Both ends of the electronic wire harness 38 are exposed with a certain length to facilitate the connection of the main circuit board of the processing element 24 and the circuit board of the audio acquisition element 12. Finally, through the encapsulation process, a layer of soft material is coated on the outside of the shape memory alloy 37 skeleton and the electronic wire harness 38 to form the sheath 39.

[0087] Among them, a through hole is provided on the microphone housing 23. One end of the electronic wire harness 38 is connected to the processing element 24 by extending into the interior of the microphone housing 23. At the same time, the shape memory alloy 37 framework is inserted and fixed with the through hole. A through hole is also provided on the sound receiving housing 11. The other end of the electronic wire harness 38 is connected to the audio acquisition element 12 by extending into the interior of the sound receiving housing 11. At the same time, the shape memory alloy 37 framework is inserted and fixed with the through hole. Thus, the mechanical connection and wire connection between the microphone main body 20 and the sound receiving assembly 10 are completed through the connecting piece 30.

[0088] See Figure 10 , in some embodiments, the sound receiving assembly 10 includes a sound receiving housing 11 and an audio acquisition element 12 installed on the sound receiving housing 11. The audio acquisition element 12 is used to acquire audio signals. Among them, the audio acquisition element 12 includes a diaphragm device. A plurality of sound receiving holes 13 can be provided on the sound receiving housing 11. The sound receiving holes 13 are arranged corresponding to the diaphragm device to improve the sound receiving effect. The sound receiving holes 13 can be in various shapes such as strip holes, round holes or square holes, and the present application does not limit this. In addition, a windproof hole 14 spaced from the sound receiving holes 13 is also provided on the sound receiving housing 11, so as to facilitate the installation of a windproof sweater through the windproof hole 14, prevent plosives and enable the wireless microphone 1 to perform sound receiving work in strong wind weather.

[0089] In some embodiments, to facilitate the assembly of the sound receiving housing 11 and the audio acquisition element 12, the sound receiving housing 11 can be formed by splicing at least two half-housings. The formed sound receiving housing 11 has a cavity, and the audio acquisition element 12 is fixedly arranged in the cavity to protect the audio acquisition element 12. As an example, the sound receiving housing 11 includes an upper housing and a lower housing, and at least one of the upper housing and the lower housing is provided with the sound receiving holes 13. It can be understood that the fixing methods of the connecting piece 30 with the microphone main body 20 and the sound receiving assembly 10 include but are not limited to effective clamping methods such as half-split clamping fixation and through-hole gluing fixation, and the present application does not limit this.

[0090] In some embodiments, to facilitate the formation of a sound receiving connection hole 15 on the sound receiving housing 11, the upper and lower housings of the sound receiving housing can be respectively provided with two semi-circular notches to be spliced and assembled to form the sound receiving connection hole 15, so that one end of the connecting piece 30 can be inserted into the sound receiving connection hole 15 for fixation, and the electronic wire harness 38 can also enter the sound receiving housing 11 through the sound receiving connection hole 15 to be connected to the audio acquisition element 12.

[0091] See Figure 11 , the microphone main body 20 includes a microphone housing 23 and a processing element 24. The processing element 24 includes elements such as a main circuit board and an antenna. A main body connection hole 25 is provided on the microphone housing 23 to facilitate the connection of the connecting piece 30. At the same time, an indicator light is provided on the microphone housing 23 to indicate that the microphone main body 20 is in a working state or a standby state, or to indicate the power state of the microphone main body 20.

[0092] See you later Figure 6 , in some embodiments, to improve the connection stability between the connector 30 and the microphone housing 23 and the sound collection housing 11, the connector 30 includes a collection connection portion 32 connected to the sound collection connection hole 15 and a receiving connection portion 33 connected to the main body connection hole 25. Among them, in the direction from the bottom end 20b of the microphone main body 20 to the top end 20a of the microphone housing 23, the collection connection portion 32 and the sound collection connection hole 15 are in a smooth transition. As an example, the outer walls of the collection connection portion 32 and the sound collection connection hole 15 gradually expand outward to increase the connection area between the connector 30 and the sound collection component 10, thereby improving the connection stability between the connector 30 and the sound collection component 10. At the same time, the outer surface 34 of the collection connection portion 32 and the sound collection connection hole 15 has a smooth line, which can also increase the aesthetics. Correspondingly, in the direction from the bottom end 20b of the microphone main body 20 to the top end 20a of the microphone housing 23, the receiving connection portion 33 and the main body connection hole 25 are in a smooth transition. As an example, the outer walls of the receiving connection portion 33 and the main body connection hole 25 gradually expand outward to increase the connection area between the connector 30 and the microphone main body 20, thereby improving the connection stability between the connector 30 and the microphone main body 20. At the same time, the outer surface 34 of the receiving connection portion 33 and the main body connection hole 25 has a smooth line, which can also increase the aesthetics.

[0093] Refer to Figure 6 , in some embodiments, to improve the wearing stability of the wireless microphone 1, the wireless microphone 1 includes a positioning assembly 50, and the positioning assembly 50 includes a positioning member 51 and a positioning mating member 52. The positioning member 51 is disposed on the clamping surface 21 of the microphone main body 20. The positioning mating member 52 is disposed on the side of the sound collection component 10 opposite to the clamping surface 21 of the microphone main body 20. The positioning member 51 and the positioning mating member 52 are detachably connected.

[0094] It should be noted that the positioning member 51 can be disposed on the clamping surface 21 of the microphone housing 23, and the positioning mating member 52 can be disposed on the side of the sound collection housing 11 opposite to the clamping surface 21 of the microphone housing 23. In this way, through the positioning assembly 50, the clamping force on the clamping object 60 in the clamping space 40 can be further improved to enhance the clamping effect on the clamping object 60, improve the wearing stability of the wireless microphone 1, and prevent it from falling off.

[0095] As an example, the positioning member 51 and the positioning mating member 52 can be set as magnet components that can attract each other. On the one hand, the magnet components are convenient to disassemble and assemble, and on the other hand, the magnet components can be set as a planar structure to reduce damage to the clamping object 60. Of course, in other embodiments, the positioning member 51 and the positioning mating member 52 can be set as a plug-in fit, and the present application does not make any restrictions.

[0096] In some embodiments, to further improve the wearing stability of the wireless microphone 1, the wireless microphone 1 further includes an anti-slip member disposed on the inner wall of the clamping space 40. It should be noted that the anti-slip member can be set as a plurality of convex structures protruding from the inner wall of the clamping space 40 to increase the friction between the clamped object 60 and the inner wall of the clamping space 40, restricting the movement of the clamped object 60 in various directions within the clamping space 40 (such as along the height direction and width direction of the microphone body 20), thereby improving the wearing stability of the wireless microphone 1. Of course, the anti-slip member can also be a silicone structure to roughen the inner wall of the clamping space 40, increasing the friction between the clamped object 60 and the inner wall of the clamping space 40, and thus limiting the clamped object 60. The structure of the anti-slip member is not limited in this application.

[0097] Regarding other structures of the portable signal acquisition device 1, this application will not elaborate. In addition, regarding the principles of other devices such as action cameras for the portable signal acquisition device, this application will not elaborate either.
